10 all whom; it may concern.

Be it known that I, J OSEPH ALGER, a. citizen of the United States, residing at Brookton, in the county of Plymouth and Commonwealth of Massachusetts, have invented certrain new and useful 1m rovements in Bore Covering Machines, of w ich the following is a s ecifiostion; his invention relates to machines For covering paper boxes, and particularly to that class of machines in which the covering-paper is applied in a single hlsnk to the hottom and folded about the sides of the box to paste the same in place.

It has been difficult heretofore with any of the machines in use to apply the paper neatly and evenly and also to arrange machines for the greet varieties of shape and size for which demand is made.

The object of the present invention to produce a. meehine which will not only ail'ord a superior and satisfactory means of performing this somewhat difiicult o eration, but which wiii he ospehle ol' hunt ling boxes or various and shapes and maybe easily and profitahly adapted to the various styles of Work within the short time availehle on small rush orders of odd patterns.

To this end the present invention contemplates-the employment of certain arrange rnents and movements of parts and the use of certain adjustments and substitutions oi members by which plain or extension-edge boxes may he covered and accommodated,

though of dilioring length, breadth, or depth,

and Whether the coveringqmper to he applied as a close-fitting sheet, as in tlrdsitension-edgo box, or as s loose-fittingwrapper, as in the type of box known as the pselrsge end The particular means by whieh these resuits are accomplished will he more fully described in the specification following andv the accompanying drawings, in which like letters of reference indicate corresponding parts throughout. end in wloch Figure 1 is general perspective View oi the machine Fig. 2, a central section through the sidefolder in its open position; Fig. 3,}; similar section through the side-folder swung up and the roll-slide depressed. Fig. 4 is a perspective detail of the ond-turnerg l ig. 5, a doteil of the edge-turning roll; Fig. 5, an end VlBW of the reinovshle block-soothers for en extension-edge hoX; Fig. 7, a View of similar parts for 2. plain box. and Fig. 8 is a rear view oi' the turner shown in Fig. i.

A is a. bed having any suitable means of support, as legs A, upon which bed are brackets B, slidshly mounted in grooves o and adjustahly held by bolts 12 in slots in the bed-plate A. The braekets B have on their inner faces shoulders B, {see Figs. 2 and 3,) to which is removahly secured by screws a.

and ooyering-psperwhon they are in place to be operated upon. Hinged to each of the brackets B is a side-folder D, to which is removshly gored by screws 2. block E. The folder s slotted at d, and adjustshly mounted'therein is a slide F, which consists of the slide portion proper, and sd-iustehly bolted thereto lay a. holtf' and a slotf is s. bracket F, upon which is pivoted an arm G, carrying it roll g at its inner end. This roll is normally pressed against the inner face of the block E by e spring- G pressing against the ()PllUSilZ-B end of the arm G. The spring G surrounds and is guided by a bolt g, mounted in the bracket F, and acts between said hrsehet sss said opposite end of G. The rolls 9* are short sectional memhers strong on an adjustable bolt, on which their turn. By removing or adding these sections the totel length of the roll proper ma be varied to meet the requirements of the mac. 9 represents n pair of look-nuts upon the end of the song, which limit the extent of the reeveinset, of the roll 9 on the block E or hold it own from, said block altogether, eooording: ;to the thickness of the box side over which it must pass. The slide F is normally held out or swsv from the hex-support to which the folder is hinged by a. spring F ll is an arm ediusishly mounted, by means of set-screws and collars, on the shaft J. This arm has pivoted at h a blade ll, which is extended to the roan and continued in a slnmk IF, which it spring h normally keeps pressed inward to direct the plate ll slight y outward to clear the edge of the box in its the end of the sums. lhe arm H hold in a. backward position lay the spring X, which is fastened stone end to the arm and at the other to one of the collars. The arm is operated 1):; eontsfot with the block T against which it yielr'iingly held by the spring X.

l is n piungor normally hold out by the spring and located in the block I This block is auliustahly mounted upon and is coir nested to the folder I) by a screw and slot,

ii is screw having lock-nuts k and is 'hlock whieh forms the support for the hex.

{Q3 movement forward to turn the paper shout 7 ta ped through a block Y, which is adjustab y mounted on the pivot p. This screw has a conical point K, which engages the end. of the plunger I as the slide F descends in its slot to press in said plun er and bear upon the end H of the turner I to tip the same and press it against the end of the box.

Fixed upon the shaft J above mentioned is a bell-crank L, which is t nnecird by a link L to the side-folder D and by a second link I to a slide M. The slide M is slotted at m and carries a stud N, which is adjustable along said slot in. The link 11 is also slotted at its lower end, as indicated at I. and said stud N asses through said slot 1, so as to loosely slide in the same. It will be readily seen by the drawings, Fig. I, there are two slides M, each connecting at opposite sides bypairs of links to the side-folders and rollslides. The structure and function of these sides are the same, so that in this description only one need be described. The operation of the side-folders is in pairs and is identical, so that in the description only one folder or set of folders need be considered. It may be well to state, however, at this point that the folders on the long side of the box are accompanied in their action by the end-turncrs, which are not present in connection with the short side-folders, (or, perhaps more properly speaking, end-folders.)

O is a spring connection between the link L and the stud N to normally hold said stud against the upper end of said slot 1. This spring has the function of allowing the folder connection to yield to allow the slide M to continue in its downward .ath and secure the necessary straight pull own on the roll slide, and also it acts as a general safety device in allowin the yielding of the parts in case the sidefolders get jammed.

P is a second link pivoted at p to the rollslide F at one end and at the other end being also slotted at p to receive the stud N, which also works looselv in said slot. The slide M works on a rod and is operated by treadles R and adjustable connections R, said parts being normally held in a raised position by the springs S. j

Y is a guide-rod for the slides M to prevent their swinging about the rod In Fig. 6 a part of the brackets B are shown as supporting a. block C. This is preferably a plain block cut to it the bottom of i the box to be covered, and as the same may be of soft wood it can be easily and quickly repared of any size which may be required.

1e blocks E are preferably likewise of wood and are usually supplied in strips which may be sawed into the proper lengths to fit the sides of the box. Tiui'c are two general types of boxes which are covered in this ina chine the extension-edge box, as indicated in Fig. 6, and the pla n box, as indicated in i Fig. 7. The box is indicated in place in Figs. l

1, 2, and 3 and in said last two named fi ures is shown as an extension-ed 6 box. Tf a plain box is to be covered, a b 00k of the thickness indicated in Fi 7 at C is employed, which rises to the Tevel of the hinges of the side-folders. The side-folding blocks E in this case are plain blocks which merely meet the edge of the box C when the folder is swung up. As shown in Fig. 6, the block t, which supports the extension-edge box, is slightly thinner than the box C and does not rise to the level of the hinge, but leaves a depressed surface which corres ends to the thickness of the extension-bot om. In this case when the folders are open the hinges form about said support a ridge which aids in centering the box thereon. With the extension-box, moreover, the side blocks E are made slightly thicker, as indicated by the dotted line e in Fig. 6, which thickened portion accommodates the extension edge and bears down upon the same with its lower face and against the side of the box with its side. As stated above, these blocks 'can be easily prepared of any length, breadth, or thickness to accommodate boxes of any length, depth, or with or without extension ed es.

The operation. of the machine is as follows, it having been adjusted to the size of the box to be covered and. being provided with suitable blocks. The operator places a box, to the bottom of which a covering-sheet has been attached, upon the boxsupport C. The treadle is then depressed, which controls the slide M, to which the side-folders are connected. As this slide M descends it draws tl'irough the link and spring connection 0 upon the bell-crank L to throw up the sidefolders against the side of the box, thus pressing the paper in place. The end-turner H at the same time is swung forward bv the engagement of the block I on the side-folder therewith to bring the covering-paper around the corner of the box and, if the same is not a flopped blank, to give it the proper fold, so that it will not wrinkle when the end-folder rises. As soon as the side-folderhas swun up snugly against the box and the end-turner as reached its utmost position the link P, having been brou ht up to a vertical position by the upward swing of the folder, will be caught at the bottom of its slot p by the stud, and as the treadle continues to descend the spring 0 yields to allow the stud N to move down in the slot Z, and the link P will be drawn down to move the roll-slide F in its slot. As this slide moves down in its slot the roll 9 encounters the edge of the box and that portion of the coverin -pa er which extends -above the same and w ch is to be turned in. At this point the spring G yields to allow the roller to ride over the edge of the box, at the same ti me firmly pressing it against the same to paste the paper against the inside of the box, as above indicated. As the slide F descends the conical point K of the screw K, which is mounted thereon, meets the end of the plunger 1, and it iasses b the same it presses it in and a sinst t e end 0 thelever H totip the late I and press itfirmly against the end 0 the box, thus making certain the adhesion of the aper to the box. As the treadle is released it is returned by the spring S and the parts resume their normal position in the reverse of the order above named. The second treadle is now depressed, which moves .the slide M which controls the folders at the end of the ox. The movement of the parts here is the same, except that there is no endturne'r and that in covering a packageend box the folder has extra thickness of paper with which to deal.

The folders of this machine ma be otherwise mounted than as shown, an the parts may be variously operated and comics-ted. Various parts may also be omitted and obvious mechanical equivalents may be substituted without departing from the spirit of myrgnvention.

. e machine may be operated by treadles, as shown and described, orconnected suitably to a raver-shaft. The removable blocks may a so be given various shapes and cut to various sizes and me be furnished in regular sets or made for t e machine, as circumstances require.
